About the Airtac SAI40 Standard Air Cylinder SAI40BX30S
The AirTAC SAI40X30-S is a double-acting ISO 15552 profile cylinder engineered for compact linear motion. Delivering 628N of push force at 0.5MPa and 528N of pull force, it is designed for short-stroke automation tasks. The extruded aluminum barrel is tie-rod-less, offering a clean exterior while maintaining strict ISO 15552 mounting interchangeability.
This specific configuration features a SUS304 stainless steel rod (code B) for superior corrosion resistance in washdown or chemically active settings. Equipped with a magnet (-S), the barrel includes dual-sided sensor grooves for direct mounting of CMSE or DMSE switches. Ports are PT tapered threads, and standard adjustable air cushions at both ends ensure smooth end-of-stroke deceleration.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX30S Is Used
Short-Stroke Clamping
Provides robust 628N holding force for securing lightweight machined components during secondary milling or drilling operations.
Package Ejection
Rapidly pushes small cartons or products off a high-speed conveyor belt using its 30mm stroke and 800mm/s maximum speed.
Valve Actuation
Shifts process valves in food-grade equipment safely, leveraging the SUS304 stainless steel rod for moisture resistance.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX30S the Right Cylinder?
Choose this 40mm bore when a 32mm bore (402N push at 0.5MPa) lacks sufficient thrust, but you want to avoid the larger footprint of a 50mm cylinder (982N push). The 30mm stroke is optimal for high-cycle clamping or ejection where travel distance is minimal. Because the stroke is short, rod-bearing side-load bending is negligible, but always ensure the load is axially aligned to prevent premature seal wear. For applications requiring the load to stay fixed without continuous air pressure, note that this standard cylinder will drift; utilize the SAIL locking variant or an external pilot check valve for fail-safe holding. Direct replacement compatible with any ISO 15552 mounting interface using FA/FB flanges or LB foot brackets.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI40 Standard Air Cylinder SAI40BX30S FAQ
